Automation Package
|
Interface-it software and RS-232 computer interface are available for setting the bath temperature via an external computer. For IEEE-488, add the 2001-IEEE to the automation package. (Interfaces not available for Model 7011.)

Hart Scientific’s temperature calibration baths are known around the world as the best calibration baths made. If you’re looking for a cold bath, no one gives you more choices than Hart.
These six baths operate at temperatures as low as –40°C, and each one is built using CFC-free refrigerants. Hart’s proprietary controller design and unique tank construction produce bath stabilities to ±0.001°C or better. These baths are so stable and uniform that national labs use them for comparison calibrations and fixed-point cell maintenance.
Each bath is fully automatable with a bath interface package and one of Hart’s automation software packages. When we automate a bath, we automate it completely with computer-controlled solenoid valves for precision balancing of the heating and cooling system. Our optional Calibrate-it software package performs all calibration tasks automatically, using your PC.
With a Hart cold bath, you can forget external coolants. The complete range of each bath is 100% covered by internal refrigeration.
Not only are these the best-performing calibration baths in the industry, they’re also the most reasonably priced. Hart is the largest manufacturer of temperature calibration baths, and larger volume means better pricing.
Each bath has unique characteristics that make it perfect for specific jobs. Some baths are excellent for SPRTs, some are great with thermistors, and some are perfect for maintaining triple point of water cells. Regardless of your application, Hart has a bath that gets the job done, and done better than anyone else can do it. Call us today and tell us about your application.
Most cold baths may be ordered with an optional pumping lid for external cooling requirements.
